DOOR HOLDER.

Application filed September 19, 1921. Serial No. 501,550.

To all w]: am it may concern Be it known that I, EMILE FRANOKAERTS, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Door Holders, of which the following is a specification.

The present invention relates to improvements in door holders of the type exemplified in U. S. Letters Patent, Numbers 1,100,475 and 1,157,376, issued to me on June 16, 1914 and October 19, 1915, wherein said holders provide for holding a door in open position and may be set and released at will.

The primary object of the present inven tion is to generally improve door holders of the character described so as to render them more durable, less expensive and easier to manufacture, to eliminate objectionable noises heretofore occasioned in releasing the holders and to reduce the number of parts employed, there being specially constructed and relatively arranged parts which facilitates assemblage and disassemblage and renders the holder more compact and strong. I

The invention possesses other advantages and features some of which, with the foregoing will be set forth at length in the following description where I shall outline in full what form of the invention which I have selected for illustration in the drawings accompanying and forming a part of the present specification. In said drawings I have shown one form of the construction of my invention, but it is to be understood that I do not limit myself to such form since the invention as expressed in the claims may be embodied in a plurality of forms.

Referring to the drawings:

Fig. 1 is a perspective view showing my device applied to a door.

Fig. 2 is a vertical sectional view of the device.

Fig. 3 is a fragmentary rear elevation of the device.

Fig. 4 is a plan view of one of t.1e parts of the holder.

Fig. 5 is a fragmentary side elevation showing the shoe or stop member reversed.

Fig. 6 is a rear elevation of the shoe.

Fig. 7 is a cross section particularly showing the manner of slidably connecting the slide with the base.

Referring to the embodiment of the in! vention illustrated in the accompanying drawings, 1 designates a base member which gage upon one face of a door, as shown at A, the member being held in place by screws 4. V

. A slide member 5 inthe form of an elon gated casing is slidably mounted upon the base member 1. The member 5 is provided on opposite edges of one side with outwardly turned flanges 6 which are adapted to slidably engage. within keepers 7 formed in spaced pairs upon the body 2. of the base member, The flanges 6 and 7 areformed by being. struck from the metalv of which the slide and base are formed and then bent into form to provide for slidably holding the member 5 in place. Upon the lower end of' the member 5 there is'pivotally supported a stop member or shoe 8 arranged so as to contact with the floor over which the door is movable, said member being moved into and out of contact with the floor bysliding movement of the member 5. i

The upper end of the slide member 5 has-a head 9 mounted thereon. Depending fromthis head and extendingwithin the member 5 is a rodlO heldby a screw 11,

upon the head. The rod 10 has a helical expansion spring 12 mounted thereon. The lower end of'the spring engages a cross piece 13 extending transversely across the member 5 but spaced from said member. The cross piece 13 is formed with an opening to permit the rod 10 to slide therethru freely. One end of the member 13 is reduced as at 14 and engages in an opening 15 therefor formed in the body 2, whereas the other end of said member 13 engages in a depression 16 formed in the outer wall of a substantially U shaped casing 17, which latter embraces themember 5 and is secured to the base 1. The casing 17 is open at both ends and upon its rear side has bendable tongues 18 which extend thru openings 19 in the body 2'and are bent over so as to hold the casing in place. A cross piece 20, similarto the cross piece 13, is carried by the casing 17 and body 2, extends thru the member 5 and has an opening therein in which the rod-1O is slidable vertically. I These members 13 and 20 serve as guidesfor-the rod 10. A trigger or rele s ng. memb r 2..is..m9u so m tend thru the member and has an opening 23 therein intermediate oi its ends thru which opening the rod extends. The rod 10 is preferably of rectilinear outline in cross section and the opening 23 is likewise formed of rectilinear outline but of greater diameter than the rod, sufficiently to permit the rod to, move freely therethru when the trigger or member is inclined to the nor- 10 mal or horizontal position. The inner end of the trigger is loosely engaged in an opening 24 formed in the base 2, and the outer end of thetrigger is downwardly off set and extended outwardly thru an opening 25 formed in the outer wall of the casing 17 whereby the said outer end may be engaged and depressed with the foot to release the device, as will be later more fully described. The slide member 5 is formed so as to be open on opposite sides to permit the members 13, 2G and 22 to extend therethru. Between the cross piece 20 and under side of the trigger 22 is a helical expansion spring 26 which surrounds the rod 10. This spring tends to, move the spring or trigger out of normal or horizontal position such that the rod 10 will be held against moving vertically.

The upper end of the body 2 of the base formed with an outwardly struck pocket 27 open on the lower side and in which a bumper element 28 preferably formed of rubber, is held so that when the member 5 moves upwardly as in releasing the holder, the head 9 of said member will engage the bumper and cushion the upmovement of the device so that the releasing operation will be noiseless and free nfrom excessive jarring. In forming the 10 pocket 27 a tongue 29 is struck so as to extend rearwardly of the pocket and then ,downwardly whereby it may be made to embrace the bumper element 28. A similar but pointed tongue 30 is formed at the lower end of the pocket and is adapted to extend. into the bumper element so as to hold the same in place.

The shoe or stop member 8 comprises a body 31 having a dove tail socket 32 which receives a rubber tread. member 33, the lat ter having a clove tail rib 34: to engage in he socket, The body 31 is closed at one nd by a downward extension 35 and is pen at its other or rear end to permit of e inss ion of the tread element in place, Extending upwardly from the body shank 36 which is pivoted intermediate of its end upon a pin or screw 37 extending transversely across the lower end of the member 5, said shank extending into said lower end of the member 5. A lever spring i0 is fixed adjacent to one end by a screw ll to the back of the body 31 so that the adjacent end of the spring will engage the dove tail rib or the tread element and hold said tread element in the socket there-tor. The other end of the spring engages upon a rear wall 42 of the member 5 and an intermediate portion of the spring engages the curved face 43 of the shank 36 at a point just below the pivot 37. This spring holds the outer end ot the shoe or tread member in position to contact first with the floor when the member 5 is depressed so that in depressing the said member the shoe will rock and cause the entire tread surface to engage the floor.

Uperation.-The holder is fixed to the door as shown in Fig. 1 so that when the member 5 is in up position the shoe will clear the floor. To lock or hold the door in open position, after the door has been moved to desired position, the operator presses downwardly upon the head 9 with his foot and depresses the member 5 against the action oi": the spring 12 so that the lower end of the tread member will engage the floor and the shoe will rock whereby the majority of the tread surface of said member will firmly grip the floor. When the member 5 has been depressed the rod 10 has been moved thru the opening 23 in the trigger 22 and the trigger 22 is maintained in such angular position by action of the spring 26 with relation to the rod that the side of the opening 23 will bind against the rod and hold the same with the member 5 and shoe 8 in position to hold the door against opening. Any attempt to close the door after it has been locked in open position will cause the shoe 8 to rock in such manner that it will hold firmly and grip the floor and as a result the door will be positively held in the desired open position. To release the holder, the operator depresses the trigger with his foot causing the trigger to move downwardly so that the edges of the opening 23 will assume positions parallel to the faces of the rod 10 and the trigger 22 will then offer no resistance to the sliding movement of the said rod. Thus, the spring 12 which has been compressed, moves the rod 10, member 5 and shoe 8 into up or inoperative position, releasing the holder from engagement with the floor, As the member 5 nuwes into normal position the head 9 thereof" engages the bumper 23, cushions the up movement and at the same time prevents any slamming hich would otherwise occur,

noise floor gripping shoe pivoted upon the slide member and arranged to engage the floor when the slide member is depressed, spring means normally holdine' said slide member in up posit-ion and means which when the slide member is depressed will automatically lock the slide member in depressed position and which when depressed itself will release said slide member and a rubber bumper against which the upper end of said slide member engages upon release oi said slide member from depressed position.

2. A door check comprising a base member adapted to be secured to a door, a slide member mounted upon said base so as to move towards and away from the floor, a floor gripping shoe pivoted on the lower end oi 'the slide member, spring;- means normally holding the said slide member in up position means which, when the slide member is depressed will automatically lock the slide member in depressed position and which when depressed itself, will release said slide &

member and cushioning means for engaging the upper end of the slide member to cushion the return movement thereof to normal position.

S. A door check comprising a base member adapted to be secured to a door, a slide member mounted upon said base so as to move towards and away from the floor, a floor gripping shoe pivoted on the lower end of the slide member, spring means normally holding the said slide member in up position, means which when the slide member is depressed will automatically lock the slide member in depressed position and which when the means itself is depressed will release said slide member. said shoe having a rubber tread element withdrawable endwise therefrom, a leaf spring normally holding; said shoe in a certain position and having one end arranged to engage and hold said tread element against withdrawal from the shoe.
